Line Chart Template

What this template is for

This line chart template turns a list of numbers into a clean trend line you can read at a glance. It ships pre-loaded with the 2026 Brent crude oil price as a worked example — a real over-the-year ride from $61 to a $118 peak and back below $70 — so you can see how a single line communicates a rise-and-fall story far better than a table. Replace the data with your own: drag any point up or down to change its value, rename the labels, and the axis rescales automatically. Use it for prices, revenue, traffic, temperature, test scores, or any metric tracked over time.

When to use this template

• Chart a commodity or stock price over time (oil, gold, a ticker) to show the trend behind the headlines.
• Plot monthly revenue, signups, or active users for a report or investor update.
• Track a KPI week over week and share the trend with your team without opening a spreadsheet.
• Show website traffic or conversion rate across a campaign period.
• Visualize temperature, weight, or any measurement logged over days or months.
• Compare a single metric's before-and-after across a project to make the impact obvious.

How to use it

1. 1Open the template — it loads with a sample trend line and labeled axes.
2. 2Double-click the chart to open the data editor on the side.
3. 3Edit each point's label (the x-axis category) and value, or add and remove points.
4. 4Drag any data point up or down directly on the canvas to fine-tune its value.
5. 5Leave the Y axis on auto range so it always fits your data, or set a fixed min/max for a consistent scale.
6. 6Add a title, toggle value labels or gridlines, and recolor the line to match your brand.

Common mistakes to avoid

• Truncating the Y axis

  Starting the axis at a value far above zero exaggerates small differences and misleads readers. This template defaults to an auto range that starts at 0 for all-positive data — keep it unless you have a specific reason to zoom in.

• Too many points crammed together

  Twenty labels on one line become an unreadable smear. Aggregate to a coarser interval (months instead of days) or split into multiple charts when the data is dense.

• Equal spacing for unequal time gaps

  If your points are not evenly spaced in time, equal spacing on the x-axis distorts the trend. Keep intervals consistent, or label the gaps clearly so the spacing isn't read as proportional.
